COMPRESSION COCK OR BIB.

Specification of Letters Patent. Application filed July 11, 1908.

Patented June 22, 1909. Serial No. 443,062.

To all whom it may concern:

Be it known that I, ALFRED R. BONFIELD, J11, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings, State of New York,have invented certain new and useful Improvements in Compression Cocksor Bibs; and I do hereby declare the following to be a full, clear, andexact description of the invention; such as Wlll enable others make anduse the same.

he invention aims to provide an improved compression cook or bib of asimple and efficient form, which may be cheaply constructed and easilyrepaired. To this end the valve stem, the valve and the valve seat, areso made as to be removable as a single piece, from the casing of thebib, so that all of the parts which are liable to wear may readily beremoved and repaired, or, if beyond repair, replaced by new parts. Theimprovements may be employed in the original construction of bibs orcocks, or they may be employed for the purpose of repairing worn outbibs or cocks of standard con struction. I In the drawings, Figure 1 isa central section of the preferred form of the invention; Fig. 2 is aplan view on the line 22 of Fig. 1 and Fig. 3 is a central sectionshowing the application of my improvements to the repair of a bib orcook of the ordinary type.

In the preferred form of my invention, as illustrated in Figs. 1 and 2,the casing 1 does not differ from the casing commonly used, exceptingthat the annular shoulder at the upper edge of the valve seat, which iscommonly present, may be dispensed with, the opening through thediaphragm in the bib being merely a circular opening without anyupstanding flange, as indicated in Fig. 1. his casing is provided withthe ordinary cap 2 through which the valve stem passes, and with awasher 3, or any other suitable packing material. The main'features ofIn Y improvements are embodied in the valve memer 4 which has a groundvalve seat 5 which comes into place immediately above the 0rdinaryopening in the diaphragm of the bib and which communicates with achamber6 within the member 4, this chamber being in communication with theoutlet of the bib through the opening 7. The member 4 in its upper part,is screw-threaded to receive the Vt ve stem 8, which carries thecone-valve 9. It will be observed that contrary to the comcompressionbibs,

ll mon type of compression bib, the valve in y improved bib closesupwardly so that not only does the pressure of the water act in adirection to close the valve, but the surface of the valve and of thevalve seat are always subjected to a thorough washing by the flow ofwater. of the valve member 4 is )erfectly flat and located wholly abovethe d tition in the casing on which it is seated, said bottom beingmerely bored out in a suitable way to form the conical valve seat; andas the edges of the valve seat are not turned down to engage thepartition, the valve opening is made independent of the opening in thepartition, that is to say, the valve seat may be made of different sizeswithin certain limits without regard to the size of the opening in thepartition. In order that a clockwise movement of the handle may closethe valve, and a counter-clockwise movement of the handle open thevalve, as is customary in I preferably make the screw-threads on thestem and in the memher 4 left-handed, instead of right-handed, though itwill be understood that this is in no way essential to my invention,since the other features of the invention may be used without it.

In the drawings I have illustrated an improved means for securing thehandle of the ib to the valve stem. As is well known, the

handles are commonly secured to the valve stems by forming a square-headon the upper end of the valve stem which fits into a square recess inthe handle, the parts being held together by a screw which screws intothe upper end of the stem. This connection is one of the features of acompression bib which most frequently needs repair, since, if'

theholding screw becomes loose, the square corners on the upper end ofthe valve stem and in the handle become worn, so that the handle slipson the stem without turning it. To avoid thisI may form on the upper endof the valve stem, as shown in Fig. l, a'screwthread of a very smallpitch, the pitch being considerably smaller than thepitch 0f the screwthread in the member 4. These threads may be very closely fitted inbrass work. so that the handle may be tightly screwed onto the stem andthe resistance to turning made very many times greater than theresistance to the turning of the threads in the member 4, so that thehandle will of fectively turn the stem without working It will be notedthat the bottom iaphragm or parshown the annular the three loose. Itwill be understood, however, that this feature of my invention, thoughit is a useful one, is not essential to the other features and may, ormay not be used, as the particular constructor desires. r

Between the diaphragm of the bib and the lower end of the member 4, I-place an elastic washer 10, and the member 4 is of such a length that itfits tightly between this washer and the washer 3, so that when the cap2 is scr'pwed down the member 4 com resses the washer 10 to make a tightfit. T is is ordi narily sufiicient to hold the member 4 from turning,but to give additional security and in order that the member 4 mayalways be 'member to the valve-seat and it isbored out conically to forma continuation 'of the valve seat, as shown.

In Fig. 3 I have illustrated the application of my improvements to therepair of a bib of the ordinary type. In this case there is ve seat forthe downwardly closing valve commonly used. My improvements may be aplied to repair such a bib in which s on the inner wall of the casinghave become stripped, or in'which the valve seat has become worn, andsince the member a carries the valve, the valve stem, and the valvesent, it constitutes in effect an entirely new mechanism, which may bequickly and cheaply placed within a worn out bib to reair it. v What Iclaim is 1. In a compression bib, the combination iota casing havm aported partition, a member seated at its ower end on said partition andprovided above the same with a conical valve seat registering with theport of the partition, and a valve stem threaded in said. member andcarrying a fixed conical valve movable upwardly to cc-act with saidvalve seat.

2. in a compression flange 13 whichis com-- monly resent in such blbsand which forms.

.the va of a casing having a ported partition or diaphragm, a memberhaving a flat bottom seated on and located wholly above said partition'and the port therein, said bottom be ing provided with an openingforming a valve seat, and a valve stem threaded-in said member andcarrying a valve movable upwardly to co-act with said valve seat,

3. in a compression bib, the combination of a casing having a horizontalpartition provided with a port, a valve member with ailat bottom locatedwholly above said port and having an opening forming a conical valveseat registering therewith, a washer interposed between said bottom andthe partition and extending completely to the valve seat, the opening ofthe washer forming a continuation of the valve seat, and a valve stemthreaded in said member and carrying a fixed conical valve movableupwardly into the opening of the washer and'the valve seat.

In testimony whereof I a'liix my signature,

in presence of two witnesses.
